This is exact. I have the sedan full part list here (g35 07-08 and G37 09-10).
They are identical. Sport and Journey doesn't make a difference.

AWD sway bar we have is#: 56230-JK000
RWD sway bar is#: 56230-1EA0C

 

So just to get things clear, if I have an X sedan, I want to buy parts #1 and #2 on this link? This 2wd bar will be an upgrade to the one I currently have?

 

Yes and yes.

 

I ordered a Stillen rear sway bar today from Stillen. They sold it to me for $146 plus some necessary bracket for about $13. It has two places to mount it which either give it 7% stiffer than the stock sport bar, or 70% stiffer than sport bar. I have to order some bushings for a stock sport bar since mine car is an X. I'll post how it drives after I mount it.

 

Does Hotchkis sell the rear bar only, and if so, through what vendor, and at what price? The stock rear bar from the non-x is somewhat of a known quantity, but the adjustability of the Stillen or Hotchkis bars might be an advantage.

 

The pricing is decent.
Does Stillen sell them as compatible for the X? Guess not
I look forward to get your input.

 

Hotchkis will sell the rear alone direct from them but it is not cheap. IIRC their price was over 200.

 

Well, I was going to use a Stillen rear sway bar, but when I called today to see why it wasn't here yet, the salesman told me that they are on backorder! It would have been nice to know that when I ordered it Monday. I specifically recall him telling me that I should look for it by the end of the week. Today they tell me that it will be next Wed. before they get them in, at the earliest.

I cancelled that order and ordered a RWD sway bar from Grubb's Infiniti. He told me that it will ship Monday and be here Tuesday. So, there won't be a review from me about the Stillen. I swear their customer service is not what it use to be.

 

you have to change bushings for the X to install stillen rear sway bar?

 

Anytime you install a bigger bar (OE, Stillen or otherwise), you need bigger bushings.

 

Ok so if i have 2008XS will the RWD sway bar work and be an upgrade?? Looks like most just have the X.

 

I have a 2008 G35xS with a RWD sway. It is a big upgrade. There is no sway bar difference between the x and xS models. Same with the RWD cars. The journey and sport have the same sway bars.

 

Thanks..its going in Monday for new steering wheel, grill etc so I will have one ordered then.

 

When you clock on the link and then click on #2 (the bar) it goes to a page that shows 2 different bars, a 2WD and AWD. Am I supposed to choose the 2WD?

 

I have the X but want the bigger bar
